you might need more coolant

When the radiator cap is removed, the pressure inside the radiator is released suddenly, causing the water to boil explosively due to the rapid decrease in pressure. The water in the radiator is under pressure to raise its boiling point, and when that pressure is suddenly relieved, the water can boil and turn to steam very quickly, leading to an explosive release of steam and hot water.
Water boils out of a radiator and builds pressure typically due to a malfunction in the cooling system, such as a leak or a faulty radiator cap. When water leaks out, the coolant level decreases, causing the remaining water to boil at a lower temperature and result in increased pressure in the system. It is essential to identify and fix the root cause to prevent engine damage.
replace your radiator cap...
Engine coolant temperature is cooled by the radiator, moved by a water pump and controlled by a thermostat. If there are troubles with any of those components the coolant will boil Also if the head gasket goes bad gasses from combustion inside the engine will get into the coolant and cause it to boil.
No, the water in a car radiator doesn't reach a boil under normal operating conditions due to the pressurized system which raises the boiling point of the coolant above 212°F (100°C). If the system loses pressure or malfunctions, the coolant may boil and lead to overheating of the engine.

Can be the thermostat which is cheap to replace, or it might be the head gasket which is expensive.
If the electric cooling fan(s) are not coming on that may be the problem.
Excess pressure is building up in the radiator probably from a blown head gasket and is exiting through the radiator cap and into the overflow bottle.
